The human body needs a lot of calcium because it cannot manufacture any and it uses this mineral for structure and many health-related functions:

Bone consists mainly of calcium.

By weight, one-third of body protein consists of collagen. A jelly-like substance with vitamin C its most important ingredient, this jelly is dependent on sufficient calcium to set. Together these two ingredients are responsible for tissue firmness (skin, etc.).

• Any healing process requires calcium.

• A calcium deficiency results in nervous tension and irritability.

• A key ingredient for normal sleep is calcium.

• Cell walls need calcium to resist infection-related intrusions.

Sufficient calcium in the blood alleviates pain. (Calcium injections are sometimes used for excruciating pain.)

Calcium deficiencies are a primary factor in mood swings before and during menstruation, and with dental problems.

Many people over 40, especially women who have birthed children, experience calcium deficiency, often a prime cause of muscle cramps and irritability, including spastic colon and irritable bowel syndrome.
